Increasing RAM to another 8GB won't necessarily eliminate lag if you're targeting a 128-bit architecture.

The only sure way is to check another 16GB or higher kit (2x8 or 2x16 works fine). If that doesn’t resolve the problem, it’s probably a software issue—like your Windows installation or drivers. Still, it might help to try it anyway; dual-channel support is definitely better.
